SS Toruń was a bulk carrier built in 1925 in the French shipyard Chantiers Navals Français in Caen.
The ceremony of consecrating and raising the Polish flag was attended by the then Minister of Industry and Trade, the builder of the port in Gdynia Eugeniusz Kwiatkowski.
At the outbreak of World War II, Toruń was moored in the port of Gdynia as a bunker ship for naval vessels.
When, under pressure from Wehrmacht troops, the defenders of the city had to withdraw from it, they sank the ship at the entrance to the port.
It sailed under the Polish flag until 1960, when it was finally withdrawn from service and handed over to the Port Authority in Gdańsk as a floating magazine MP-ZP Gda 20.
